At this point its already known that countrys mine bitcoin as part of their "cover ops". So they wont come up and say they are mining.
so govs take control of major electrical grid and mine w it. Then introduce kyc to anyone. The fees are not matter at this point. Individual mining doesnt matter also as this point. What matter is who win those blocks, which country win those blocks.
They wont be an annoncement about gov financing/mining bitcoin, they also wont legitimize it 'cuz law around the world are "different". And like in those HW they will choose who is in and who is out.
